The length of a side of the original square is about 12 inches.
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the length of the original square, hence:
Area = x * x = x²
When the area is doubled:
2x² = (x + 6)(x + 4)
x² + 10x + 24 = 2x²
x² - 10x - 24 = 0
x = 12 inches
